d' one dirootiy through the sheet. moiotoiore in woei@ :011 is a er asses to a take- '7 'more rigid or stable, whereby they may stand up better to the action of the cutter 8.

in the application of my invention to the manufacture oi lace paper the roii 7 would ordinarilyhe the usual embossing-roll. In passing between the rolls 6 and 7 the paper would therefore receive the usual enihossings on its up er or face side, while the indentations ma 'e hy the roll 6 would appear on the reverse or under side. My invention is thus seen 'to com rise two distinct and important steps. in te rst step of my process itwill he noted that l produce an unfinished artiele-namelg/f, a paper or other material in dented on one side, but as yet uncut. This article is novel with me and is characteristic of my invention. The second step of the process consists in a treatment of the indented material to cut or divide from its body the indentation or elevation' produced in the first step.

Since in. my invention the cutting is done by removing the elevations on the surface oi indented sheet material, the necessity of punching through the sheets is obviated, and consequently my process admits of considerable selection oi4 cutting means or methods, thus making possihle more 'efficient cutting and a better iinished article. For instance, a knife-edge by its nature is likel to injure a fabric, such as paper, and vet heretofore it has heen the most practicable means for cutting, n'iny invention, however, as l simply have protuberances or indentaiions to rcmove, I prei'er to grind oil the same. The advantages of grinding are several. Grindingy involves no dies to become clogged, and it is 5 an easy matter to take care of the particles removed from the sheet. The p-.ri'orations or divisions may by grinding be made practically perfect, in that the elevations or protuberances ma he removed flush with the surface of the silent without any chance of injury to the latter. A griii lirigt ol, even if in contact with the face of the sheet, will not catch or injure the same, providing the engagement of the tool with the paper 1s to some extent yielding.

in the removal ol' the indentation by the grinder l rely on the natural si ability ol' the paper or other fabric to enable the eleva ions or protuluerances to stand up against lhc action of the grinding-tool. The lltbric being estrias assing in a sheet over the Grinder from the indenting to the taire-upl rolls wou'ld'not hy virtue of its character and the length ci? the sheet have sufficient resiliency of movement at the grinder, a further means for providing; resilient engagement oi the sheet grinder is introduced. in the present caseii have shown the paper as hearing iightly on the grinding-roll by reason of the action of the spring '9. @ther means ici' obtaining a resilient engagement of the grinder with the in dented material may of course he substituted for that shown.

W here in son-ie instances the taloric may he particularly delicate or iiimsy, i superimpose a plurality of sheets of the same before the n- 'dentingf step. The sl eets then indented, the pyramids or indents thereon being presented to the grinder in multiplex Will stand u to f the latter, so as to he cut cleanly and ertectively, no matter hojW delicate the .texture may he. fidditionai advantages oiI my method are, then, that a numher of sheets may be prepared simultaneously and that, regard of the nature oi the fabric, the paper can be divided withoutinjury thereto.

lWhereas .I have stated my invention as particularly adaptable to the manufacture oi ace paper, it is obvious that it may he equally adaptable and usei'ul in almost any instance where paper is to he divided or perforated. My invention may, for instance, he employed to great advantage in the manie facture of dress-patterns. ln such use it is merely necessary to indent the pattern-paper along the iine of the pattern to bc cut, leaving an occasional breakin the indent in order to provide means for maintaining'the pattern in the sheet until it is desirable to detach the same. Then, upon the division of the pattern-paper along the line of the indentation, the pattern will be severed, except for i the retaining-pieces lei't at the points Where the indent was broken. The dpattern may thus be made in a simple an expeditious manner by merely passing the paper through the steps of my invention hereinhefore dcscribed, and the pattern-shects emerging from the machine are at once ready ha" shipment and use. Obviously, moreover, my invention is not confined to the division or perforation of paper alone. .The invention. applicable Wherever any sheet material of a 'nature to bev indented in the manner de'- scribcd is to be cut or divided f or almost any purpose. vFor instance, by my process the ornamental trinunings oi brass or other metal used on picture-frames, furniture, and elsewhere 'are readily and effectively made.

The variety ofA the material and the purpose for Which such may be used when cut in accordance with the present invention ,are innumerable. y

What I claim is- 1. The method of cutting or dividing paper or other sheet material which consists in first indenting the paper or other sheet material along the lines Where it is desired todivide the same, and then cutting theindentations- Jfrom thel material While maintaining the latter in resilient engagement with the cutting-tool.

,2. The method of cutting or dividing paper or other` sheet material, Which consists in irst indenting the paper or other sheet material along the lines Where it isdesired to divide the same and then grinding or abrading the indentations from the material While maintaining the latter in resilient engagement with the grinding-tool.

3. The method of cutting or dividing paper or other sheet material which consists in first indenting the paper or other sheet lmaterial along the lines Where it is desired to divide the same, and then grinding or abrading the indentations until the same are reduced to a plane flush AWith the surface of the sheet While maintaining the latter in resilient engagement with the grinding-tool.

4. The method of making lace paper which consists in indenting the paper Where it is desired to cut out portions of the paper A and then'cutting the indentations from the material While maintaining the latter in re. silient engagement With the cutting-tool.

5. The method of making lace -paper which consists in indenting the paper Where it is desired to cut out portions ofthe paper, and then grinding or abrading-the indentations from the material While maintaining theiatte'r in resilient engagement with the cutting-tool.

6. The method of making lace paper YWhich consists in indenting the paper Where it is desired to cut out portions of the paper and then inding or abrading the indentations, unti the same are reduced to a plane ush with the surface ofithe paper While maintaining the latter in resilient* engagement with the grindin -tool l 7.
